I need to buy new glue brushes (well maybe). For years I had what must be hand made bristle brushes. I have also used plastic spreader type. When I was an apprentice we just used a spare wedge or scrap of wood that was available. The choice now seems to be either buy disposable brushes dirt cheap on the internet or seek out very expensive hand made brushes or go back to using a scrap of wood. What do you use and why?
